I'm into more mobile (and dry) pets but if fish float your boat, you may want to build one of these for your little buddy.........

What a neat application for computer vision! Who knew there were fish out there wanting to explore their world!!

    Pretty cool, but for the proper steering response, it needs a chassis with mecanum wheels! :)

    And could be a lot smoother, the fish probably isn't enjoying the ride!

    For a smoother experience for the fish, how about a "Fish hamster ball" ? ..... Constructed like an over sized computer mouse wheel only use conventional omni-wheels like erco suggested for the 'frame" to house the hamster ball.

    What's next? Maybe someone will put a chihuahua on a roller ball table inside a clear sealed chamber and sink it in a pond to see where he wants to explore. :)

    I was thinking the same thing in terms of mechanum wheels or some other omnidirectional movement.

    A while back I was intending to build something like this for a semi-crippled pigeon named "Waddles." But I guess that will have to be on my post-graduation list.

    If you had a good behavioral way to test to see if the fish was using the device, that would be worthy of publication. I suspect that the fish is not "intentionally" controlling the device here. Another potential issue is that I am not sure if the fish can be near the wall to "look out the side" with out also activating the motors. I put "look out the side" because who knows what the fish is really doing. I do think they can be smart, but you can't assume without testing.

    Still, cool video. I would love to have time to try something like this.

    Two fish in a tank. One says to the other "How do you drive one of these" :lol::lol::lol::lol::lol::innocent:

    This is very disturbing.

    Now I see the Genesis of the Daleks.

    This brings up some interesting philosophical questions:
    Do goldfish think?

    Do they connect cause (swimming to one end of the container) and effect (making the robot move that direction)?

    Do they exhibit volition? IOW do they swim to one side or the other becasue they actually want to go that direction? Or is it just random motion?

    An interesting study would be to place a food source at a strategic location that the fish can find... when the fish is at that location food is dispensed. Manually move the fish&car to another location and see if ...

    1) the fish recognizes where it is
    2) if there is an obvious effort to migrate towards the food source

    cool! Can the fish actually learn the room? And if so, why? What can they identify to explore the room? What is the most
    intelligent fish that could be used for the fishbot? :)

    Best keep the door shut otherwise it will be off down the road to the local cinema to watch "Finding Nemo" before you realise it!

    I was wondering about this.

    I don't know about gold fish but many fish like to swim around in shoals.

    So, if you had many such robots each with a fish, given that they could see each other would we end up with a shoal of robots running around the room?

    Certainly you can train birds, like pigeons, to peck on buttons to get food. Perhaps the humble gold fish as well.

    I think we should scale this whole experiment up to dolphin size and see if they are as smart as they are said to be.

    Slopes could be problematic for the current configuration
